There are two species of greater glider recognised. The Greater Glider (Southern and Central)(Petauroides volans) was listed as Endangered in July 2022. It occurs along the eastern coast from around Proserpine in Queensland to Central Victoria.

The expert advice that led to the Endangered listing of the Greater Glider (Southern and Central) specified logging as a major threat.

Greater gliders feed almost exclusively on leaves of certain eucalypt species. Studies in southern Queensland indicate the most important species for greater glider habitat selection are Spotted Gum (Corymbia citriodora) and Queensland Blue Gum (Eucalyptus tereticornis). Both are favoured species for timber harvesting.

Greater gliders are fundamentally dependent for shelter/denning on large hollows in large old trees.

The intensive (40cm+ diameter cut) logging practised in State Forests specifically removes all trees more than 40 cm in diameter (at breast height) except for 6 habitat trees per hectare — if they are available, which is commonly not the case.

Of great concern is the finding by researchers at Griffith University that the major part of the greater glider habitat in Queensland is outside protected areas.

It is clear that the endangered Greater Glider is is in peril and is threatened by intensive logging in Queensland’s State Forests.

Details are explained in the pages on this site.

The Greater Glider is also being impacted by climate change and the impacts can be expected to increase in the future.     More...
